2010-05-14 Lower Austria, district Bruck/Leitha (Steingschirr, 185 m AMSL).Flowering.Growing here on dry, nutrient-poor soil, which it is enrichening with nitrogen - thus, changing it to nutrient-rich, which over time will wreck the whole habitat (
this one here) where very rare Stipa pulcherrima is growing.Robinia pseudoacacia (Robinie)

Robinia pseudoacacia L., syn.: Robinia pseudacacia, Robinia pseudo-acacia L.False Acacia, DE: Falsche Akazie, Robinie, SilberregenSlo.: navadna robinija, neprava akacijaDat.: May 16. 2011Lat.: 46.32566 Long.: 13.52629Code: Bot_515/2011_IMG4891Habitat: mixed wood on alluvial terrace edge, Fagus sylvatica. Pinus sp., Picea abies, Corylus avellana, Ostrya carpinifolia dominant trees; calcareous ground, sunny place, elevation 400 m (1.300 feet); average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, alpine phytogeographical region. Place: Bovec basin, next to the regional road Bovec - village aga, East Julian Alps, Posoje, Slovenia EC.Comment: Robinia pseudoacacia is a two-faced tree of Europe imported from America in 1601, which is now common and already naturalized. It can grow up to 25 m height. On the one side it is quite an aggressive invasive species, horribly thorny and lightly poisonous. Thorns, developed from bracts, are large, strong and sharp and can cause serious injuries. On the other side, it is beautiful (when in bloom), nicely smelling already from far and a pleasure for bees (and their 'owners'). The flowers can be used as food and some consider it as a medical plant. The tree is present from lowland to montane elevations and can be found also in the whole Alps and all other European mountains.Ref.:(1) M.A. Fischer, W. Adler, K.

2008.06.23: Austria, Vienna XXII. district, 152 m AMSL, heath (Lobau Heisslnde): bark 'ringed'.This is a method to effectively kill them (and the reason for doing so is that they enrichen soil with nitrogen which changes the soil forever - as they grow on nutrient poor soil which is home to many endangered species which dislike rich soil).R. pseudoacacia, when 'ringend', still tries to support its branches and leaves till the whole tree dies off, roots included. (With some other species this however does not work, as is the case for Alianthus altissima, another introduced and invasive species equally endangering heaths.)Trees which are felled though grow new shoots from their roots: so felling is not an option to preserve this heath biotope.Flowering in may/june.Common, invasive.German names: Gewhnlich-Robinie, Scheinakazie, Falsche Akazie.For ringing method cf.

2008-05-23 Lower Austria, district Gnserndorf (Lobau bush heath - Busch-Heisslnde, 150 AMSL).The dead trees are Populus alba; to the right there's also Robinia pseudoacacia to be seen (flowering).This is a typical bush heath habitat of Lobau - dry and nutrient-poor soil on elevated rubble terraces which are usually only flooded rarely (every 10 years or so, or even less frequent; this place however has been flooded in 2002, 2009 and 2010).
